SPECIFICATION forming part of Letters Patent No. 743,702, dated November 10, 1903.

Application led September 12, 1903. Serial No. 172,875. (No model.)

To all whom it may concern: i

Beit known that I, ANDREW J. FINK, J r.,' a citizen of the United States, residing at Reading, in the county of Berks and State of Penn-l sylvania, have invented certain new and useful Improvements in Gage-Cocks; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to improvements in gage-cocks; and the .object of the invention is to provide an attachment whereby said gage-cock may be easily kept free from clogging or closing up, caused by foreign substances, insuring a positive opening therethrough, making the gage-cock absolutely reliable.

The invention consists of a plunger passing entirely through the gage-cock longitudinally, capable of being pushed forward and backward therein.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of a gage-cock, showing myimprovement. Fig. 2 is a detail of theplunger.

lis the casing of the gage-cock, of ordinary construction, having the usual valve 2 and valve-stem 3.

4 is the operating-handle for the valve.

5 is a plunger-rod which passes entirely through the gage-cock. Its one end projects beyond the handle 4 and is formed with a suitable button or handle 4J.- A stuffing-box 6 is located in the handle 4:, through which .said plunger passes. The plunger-rod passes through the valve 2, and its inner end is screw-threaded externally. Onto this screwthreaded endv is placed a conical head-piece 7, screw-threaded internally. This head-piece is cut away at one or more Vpoints '7a at its larger diameter to permit free passage of the steam or water into the casing l.Y

The gage-cock is placed in position on the boiler, as usual, and an occasional operation or movement of the plunger by the attendant will insure a free opening therethrough,

ton on the outer end and a cone-shaped headpiece on the inner end, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
